* nosh system module: fixes and improvements
documentation:
* fleshed out and fixed to better follow the official guidelines
consistency:
* the following facts will now always be returned on success: name,
service_path, enabled, preset, user, status
* state is only returned when the state option is used
* state and status will be null if the service is not loaded by the end
of the task
* [nosh]: PEP8 fix
* Add nosh service manager module
* based on the `svc`, `systemd`, `runit` and proposed `rc_service`
modules
* uses the high-level 'system-control' command and assumes nosh-native
interfaces though it should work with daemontools-style service scanning
* assumes a single service name is provided
* Metadata fixes
* Added "author" and "version_added"
* fixed the RETURN yaml
* PEP8 fixes
* fixed spacing issue
